BED-RISER.

Specification of Letters Patent. Application filed March 2, 1912.

PatentedNov. 4, 1913.

Serial No. 681,199. a

To all whom itmay concern Be it known that I, FRANCIS EUGENE SLOAN, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful improvements in Bed-Risers, of which the following is a specification.

This invention relates to improvements in bed risers for use in connection with stretcher tubes whereby to elevate the woven wire fabric spring and sustain it in a stretched condition above the longitudinal stretcher tubes. In practice two stretcher tubes are employed and each end of the tube is provided with an improved riser.

()ne object of the invention is to provide an improved construction of riser which may be quickly attached to the ends of the tubes and which will form a substantial support for the usual angle bar to which the wire fabric is secured.

Another object is to provide an improved construction of bed riser that will remain on the end of the stretcher tube without requiring a separate fastening; that will prevent the tubes from turning; that will entirely close the end of said t be and which will sustain the angle bar to which the wire fabric is secured in such a way as to avoid the necessity of the wire fabric bending around a sharp angle of the bar that secures it.

Other objects and advantages arising as a result of the improved riser will be apparent to those skilled in the art.

The accompanying drawing illustrates the invention wherein,-

Figure 1, shows a side elevation of one end of a stretcher tube to which an improved riser is attached and appears in side elevation, and also shows the angle bar in end elevation and the end of the wire fabric secured thereto. Fig. 2, shows the same as viewed from the inner side of the angle bar and shows the stretcher tube in vertical crosssection. Fig. 3, is a top plan view of the end of a stretcher tube and the riser thereon, the latter being broken away at the rear to show the device for locking the riser and tube against rotation, and Fig. 4, shows the improved riser in perspective.

Referring to the drawing by numerals, 1, designates the stretcher tube which is provided with a notch, 2, in its extreme end edge and preferably at the extreme upper portion of its circumference, as'shown in Fig. 3. Two of these stretcher tubes are employed in the stretching of awoven wire mattress or fabric,--one being located at each longitudinal side of the mattress, and both ends of each bar is provided with one of the improved risers so as to sustain the wire fabric, 3, in an elevated position with respect to said stretcher tubes.

The improved riser comprises an upright substantially rectangular body having a vertical front end wall, 4; a vertical side wall, 5, at right angles to said front end wall; a short rear wall, 6; another short side wall, 7, and a longer side wall, 8, which laps the said shorter side wall, 7 and from which a supporting flange, 9, projects in a direction parallel with the front end wall, 4.

The front end wall, 4, of the riser is of greater length than all the other walls thereof and has a curved lower end, 10, which serves as a cover for the open end of the stretcher tube, as will presently more fully appear. It will be noted by reference to Figs. 2 and 4, of the drawing, that the upper edges of the supporting flange, 9; the longer side wall, 8, the front end wall, 4, and a portion of the side wall, 5, are all flush,- the said edge of the flange, 9, however is provided with a notch, 11, also for a purpose presently to be explained.

The lower edge of the short rear wall, 6, of the riser is provided with a curved notch, 12, the arch of which is such as to conform to the curved wall of the stretcher tube, 1. The bottom or lower edges of the side and rear walls of the riser are substantially flush, but the front end wall, 4, is of greater length as heretofore explained.

A. stirrup plate, 13, of substantially a U- shape is carried at one side by the side wall, 5, and at the other side by the lapped shorter and longer .side walls, 7, and, 8, respectively,- one end, 14, of said stirrup plate being secured to the side wall,-5, in the present instance by rivets, 15, while the other end, 16, thereof is secured to the lapped side walls, 7, and, 8, by means of rivets, 17. These latter rivets also serve to rigidly secure the shorter side wall, 7, and longer side wall, 8, in a lapped position. By reference to Figs. 1, 2 and 4, it will be seen that the bend, 18, in the stirrup conforms in shape to the curvature of the lower half of the stretcher tube, 1, and forms a support for the under side and end of said tube and that the curved notch, 12, at the lower end of the rear endwall, 6, conforms to the curvature of the upper half of the said stretcher tube and it will be further noted that said latter curved notch, 12, will bear on the upper portion of the tube at'a point much farther from the end of the latter than the point where bend, 18, of the stirrup contacts with the lower portion of said tube. V The vertical front end wall, 4, of the riser is provided with a projection, 19, which extends inwardly and enters the notch, 2, in the edge of the stretcher tube, as seen in Fig. 3, and by this means the tube is prevented from rotation. I

The supporting flange, 9, which projects laterally from the lapped side walls, 7 and, 8, of the riser is preferably provided with vertical corrugations, 20, which latter eX- tend upwardly from the bottom edge and serve to stiffen said flange and also to increase the bottom contact surface when the support is placed on a side rail of a bed as is the common practice in this art.

To secure the end of the wire fabric, 3, I make use of an angle bar, 21, and said angle bar is supported at one end by a riser on the end of one stretcher tube while the other end of said angle bar is supported by a like riser on the another of the stretcher tubes. The angle bar is so placed on the risers that one flange 22, thereof will lie flat or horizontally on the flush upper edges of the flange, 9, long side wall, 8, front end wall, 4, and side wall, 5, while the other flange, 23, of said angle bar 6X- tends downwardly at against the outer surface of the front end wall, 4, of the riser and is rigidly held in close contact therewith by means of bolts or rivets, 24L, that extend through suitabl perforations in said flange, 23, of the angle bar and then project through perforations, 25, in the front end wall, 4. r

The end of the spring wire fabric, 3, is placed on the upper surface of the horizontal flange, 22, of the anglebar and a plate 26, is laid on top of the wires which latter is then drawn down by means of bolts or rivets, 27, so as to securely clamp the wire to the angle bar. By this means the pull of the wirefabric is direct from the flat flange, 22, of the angle bar. and is. therefore not drawn over a sharp angle as it would if the wire were turned down and secured to the vertical flange, 23, of the bar. The notch, 11, in the upper edge of the supporting flange, 9, forms a recess to receive the head of the bolt or rivet, 27, that must be placed at that end of the angle bar to effectually hold the wire fabric.

Obviously, when the riser is placed on the end of a stretcher tube, 1, the latter will be engaged at the under side by the stirrup,

13, while the curved notch in wall, 6, will rest upon the upper side of the tube, consequently as the wire fabric is placed under tension and stretched so as to allow the tubes, 1, to enter the risers, the mere pull of the wire fabric will hold the risers in place on the tube.

Having thus described my invention what I claim and desire to secure by Letters Patent-is,-

1. A bed riserhaving front side and rear upright end walls and the rear end wall having an edge to bear on the upper side of a stretcher tube while the front end wall projects below said bearing edge of the rear end wall, the riser also having a supporting arm that projects laterally from one side wall in a plane between the front and rear end walls and a stirrup carried by the opposite side walls and at the inner side of the front end wall to support the under side of a stretcher tube.

2-. A bed riser having'front and rear up right end walls,the front wall being longer than the rear wall, and also having lapped side walls at one side, a supporting flange projecting laterally from the lapped side walls and a stirrup depending from the inner sideof said lapped side walls and at the inner side of the longer front wall.

3. A bed riser having front and rear upright end walls of which the front wall is the longer and also having at one side a single side wall which connects the front and rear end walls and at the other side two lapped side walls, a supporting flange extending laterally from one of the lapped side walls and a stirrup plate having one end secured to the lapped side walls at one side and the other end secured to the single side wall at the opposite side.

In testimony whereof I affix my signature in presence of two witnesses.
